Definitions

  • R is an alkyl group having 2 to 5 carbon atoms including an unsaturated bond
  • the superabsorbent polymer composition contains a carboxylic acid having a structure of A-(EO) m -COOH and a compound having a structure of HO-B 2 -C. may include more.
  • the superabsorbent polymer composition of one embodiment includes polyethylene glycol, polypropylene glycol, poly(ethylene glycol)-poly(propylene glycol) copolymer, polyoxyethylene lauryl ether carboxylic acid, sodium polyoxyethylene lauryl ether carboxyl It may not contain hydrophilic additives such as lactate, lauryl sulfate, sodium lauryl sulfate, and the like. Since these additives do not have the (B 1 -B 2 ) moiety of Formula 1 in the molecule, they cannot be sufficiently adsorbed to the surface of the cross-linked polymer, so that aggregation between the super absorbent polymer particles is not effectively suppressed.
  • hydrophilic additives such as lactate, lauryl sulfate, sodium lauryl sulfate, and the like. Since these additives do not have the (B 1 -B 2 ) moiety of Formula 1 in the molecule, they cannot be sufficiently adsorbed to the surface of the cross-linked polymer,
  • the superabsorbent polymer composition may be prepared by crosslinking and polymerizing a water-soluble ethylenically unsaturated monomer having an acidic group at least partially neutralized in the presence of an internal crosslinking agent and a polymerization initiator to form a hydrogel polymer; mixing the hydrogel polymer with the carboxylic acid-based additive and pulverizing the hydrogel polymer to prepare a pulverized product containing the water-containing superabsorbent polymer particles and the additive; and drying the pulverized product to prepare a superabsorbent polymer composition including the superabsorbent polymer particles and the additive.
  • the step may include preparing a monomer composition by mixing the water-soluble ethylenically unsaturated monomer, an internal crosslinking agent and a polymerization initiator, and thermally or photopolymerizing the monomer composition to form a hydrogel polymer.

Abstract

La présente invention concerne une composition de polymère superabsorbant. Plus spécifiquement, la présente invention concerne une composition de polymère superabsorbant qui est préparée pour contenir un additif ayant une structure particulière afin de supprimer l'agrégation entre des particules de résine, un procédé de pulvérisation supplémentaire n'étant ainsi pas nécessaire après un procédé de séchage.
